Type Size Constants

Are there any defined constants for the min and max sizes of the primitive types such as

Const MaxInt:Int = (2^31)-1
Const MaxDouble:Double = 10^308
Const MinDouble:Double = 10^-308
Const MaxFloat:Float = 10^38
Const MinFloat:Float = 10^-38

is that a question?

Yes, if I can use bmax defined consts then I don't need my own.
